NAME
hide_panel,
show_panel, panel_hidden
— visibility of
panels
LIBRARY
library “libpanel”
SYNOPSIS
#include
<panel.h>
int
hide_panel(PANEL
*p);
int
show_panel(PANEL
*p);
int
panel_hidden(PANEL
*p);
DESCRIPTION
Panels are initially created visible. The functionhide_panel()
can be used to hide a panel. The panel is removed from the deck.
A panel can be made visible again with a call to
show_panel().
The panel is returned to the top of the deck.
IMPLEMENTATION NOTES
The show_panel() function will return an
error if the panel is already visible. Use
top_panel(3) to change z-order of an already visible panel. This is
the behaviour specified by the original AT&T
System V UNIX panel library.
In the ncurses implementation of the panel library
show_panel() and top_panel()
are identical and handle both visible and hidden panels. This may be a
source of bugs in programs tested only against ncurses.
RETURN VALUES
The panel_hidden() function returns
TRUE or FALSE. It will
return ERR if passed a null pointer.
Other functions will return one of the following values:
OK- The function completed successfully.
ERR- An error occurred in the function.
